I recently failed a smog test, They said that my HC'S were to high supposed to be around 220 and mine were around 500 to 600parts per million. I already did a tune up spark plugs and wires plus a oil change,air filter,oil filter,and gapped the spark plugs @ 0.060 inches like the manuel specified!!!!
